IMPROVEMENT IN coNs'rRUcTloN oF.sA|L|NG -v|:ssELs.

Specification forming part of Letters PatentNo. 180,690, dated August 1, 1876; application filed July 17, 1876.

-To all whom it may concern:

l independent keel as pivoted to the ends of the hull.

My present improvements relate to a vessel embodying the same general principle, but I so modify the structure as to render it feasible to use one or more masts not located at the extreme end or ends of the vessel. I also make provision for raising up the keel, whenever this is desired, for purposes hereinafter stated. f

Instead of arranging pintles orv pivots at the extreme ends of the vessel, I now, in effeet, make the body ofthe vessel the pivot on which the independent keel can move as an axis, friction-.rollers being used, if necessary, to diminish friction between the parts. I also joint the vertical bars, from which the horizontal. independent keel proper is suspended, so that the latter may mo've to and from the hull as one, part of a parallel rule moves to and from the other part.

vThe nature of my improvements and the manner in which the same are or may be carried into effect will be understood by refer ence to the accompanying drawing, in which- Figure 1 is a side elevation of a two-masted schooner-rigged vessel, embodying` my invention. Fig. 3 is a transverse vertical section of the same. Fig. 2 is a side elevation of a like vessel representing a modied form of the structure, which I term the independent keel, and also a modified form of the joint which unites it with the hull. Fig. 4 is a transverse vertical section of the modification shown in Fig. 2'.

A is the hull, of any suitable structure and configuration. In this instance it is shaped to resemble the cigar-vessel, so called. The independent keel B consists of the bottom -keel proper,

which the masts are fitted and firmly secured The sails and masts can thus give to the wind without thereby tilting the hull or rendering it liable to capsize. The upright connectingbars c are jointed, at g, to the independent and at f to the straps d, as shown; and to a projection, h, on the lower end of the forward bar is connected a rope or chain, z', which leads to the deck of the ves' sel, and may, be combined with pulleys and tackle, by which the rope may be drawn, so

as to swing the bars d backward, and so elevate the independent keel, as` indicated in `dotted lines in Fig. 1.

By this arrangement large vesselsmay, by raising the keel, enter ports having comparatively shallow water, and still., avail of the deep water of the ocean to obtain *enormous lateral resistance for sail-power from the keel when lowered. In Figs. 2 and 4, instead of annular straps encircling the hull, I make use of what may be termed saddle-piecesj, which rest on and fit the top of the hull, or bea-rings thereon, and are combined with side braces or stays 7c, which extend down from each side of the saddle-pieces below the vessel, and converge, so as to meet in a keel, Z, some-little distance below the hull. The angle of convergence of these braces is such that they touch, or closely approach, the hull at a point below the longitudinal axis of the same, thus serving to hold the saddle-piece on its seat,

and to prevent its lifting therefrom. Below the keel l is the second or main keel b, connected therewith by the jointed bars c, and arranged like the keel b be raised and lowered, as indicated by the dotted lines. l

Having now described my improvements The in Figs. 1 and 3, to i and the manner in 'which the same are or 'may be carried into effect, what I "claim and desi-re to secure by Letters Patent, is-/ the hull, or on bearings formed thereon, aty

two or more points intermediate between the ends of the same, so as to be capable of lateral vibration i1rdependentlyof said hull, sul)` stantially as and for the purposes set forth.

2.v The combination ofthe hull, the independent keel proper, the vertical connecting;- bars, and the annular straps, or their specii'ed equivalen-ts, encircling the body of 'the hull, or hearings thereon, substantially as `s'e'tvforth. 3. An independent-keel, carrying the masts e .and sails, capable of lateral vibration independently of the hull, and vertically adjustable nearer to or farther from the hull, substantially as and for the purposes set forth.

In testimony whereof I have hereunto signed rmy name this 15th day for July, A; D. 1876.

THOMAS WINANS.
